NOTE
Rope will stretch and shrink in
diameter when loads are applied,
Apply the initial load and retighten nuts to the
recommended torque. Inspect periodically
and retighten.
A termination made in accordance with the
above instructions, and using the number of
clips shown, has an approximate 80% effi-
ciency rating. This rating is based upon the
catalog breaking strength of wire rope. If a
pulley is used in place of a thimble for turning
back the rope, add one additional clip.
NOTE
The following information is
based upon the use of U-bolt
clips on new rope.
The number of clips shown is based upon
using right regular or lang lay wire rope, 6x19
class or 6x37 class, fibre core or IWRC, IPS
or XIPS. If Scale construction or similar
large outer wire type construction in the 6x19
class is to be used for sizes 1 in. and larger,
add one additional clip.
The number of clips shown also applies to
right regular lay wire rope, 8x19 class, fibre
core, IPS size 1-1/2 in. and smaller; and right
regular lay wire rope, 18x7 class, fibre core,
IPS or XIPS, sizes 1-3/4 and smaller.
For other classes of wire rope not mentioned
above, it may be necessary to add additional
clips to the number shown.
If a greater number of clips are used than
shown in the table, the amount of rope
turnback should be increased proportionately.
Fist Grip Clips
Failure to make a termination in
accordance with the following
instructions, or failure to periodi -
tally check and retighten to the
recommended torque, will cause
a reduction in efficiency rating,
which could cause DEATH or
serious injury.
Refer to Figure 4-37 and Table 6 (page 4-40) for
specifications of fist grip clips.
The recommended method of applying fist grip
clips is as follows:
1. Turn back the specified amount of rope from
the thimble. Apply the first clip one base
width from the dead end of the wire rope.
Tighten nuts evenly to recommended torque.
2. Apply the next clip as near the loop as pos-
sible. Turn nuts firmly but do not tighten.
3. Space additional clips, if required, equally
between the first two. Turn nuts, take up rope
slack, and tighten all nuts evenly on all clips
to recommended torque.
